Step 1: PVC pipe

2-Using a template, to where I want the hole so the pipe did not travel past the rim, I simply drilled the hole (as shown in the photos)

3-I laid the 1/2 pipes down alternating ends. We all know that the pvc has one end wider than the other to be able to fit to each other (phlange)

That was it for the pvc..really ...that was.

Step 2: Bike Rims

It takes 3 to tango on this one.

1-The rims are all the same size 12"

2-I removed the spokes on one side only

3-I left the top Rim as is and used the rim's axel as a bearing

4-I left the middel one as is

5-I drilled the bottom Rim out or cut off the axel cover including one end(shown in photos)
I then placed a piece of plywood on the bottom for support and cover for the generator. To find the centre, you simply use a thread and wind it through the removed spokes, and where they meet you will see a star and in the centre of the star is your mid point.

WRONG WRONG DON'T GO OFF ON THE ALTERNATOR PATH BECAUSE YOU THEN HAVE TO SUPPLY ENERGY TO THE ALTERNATOR AND ONLY WHEN THE WIND IS BLOWING OTHER WISE IT DRAINS THE BATTERYS. GENERATORS DONT REQUIRE ELECTRICITY TO CREATE ELECTRICITY. THE WORLD BEST SELLING WIND GENERATOR SELLS FOR $500 ON NORTHER MACJINERY WEB SITE THE AIR TURBINE HAS A NEODYNIUM GENERATOR AND IT CAN BE PURCHASED SEPERATE AND APART FROM AIR WIND GENERATOR. IF GRANDPA WOULD GIVE YOU HIS OLD OLD CAR YOU COULD JUST SELL IT ON E-BAY FOR TWO GRAND AND BUY FOUR BRAND NEW UNITS. OR DO LIKE THIS OTHER GUY ON HERE AND BUY A OLDER ECONOMY CAR GEO METRO AND CONVERT TO ELECTRIC. HE BOUGHT FOR $500 THEN SOLD THE OLD GAS ENGINE FOR $500 NICE TRICK DUDE FREE RIDE. I'LL WORK ALL SUMMER FOR A FREE RIDE.

I just finished answering you on the last project. I see you are full of advice. I am always on the move, and I know about all the gadgets that you mentioned, testing is always on when it is not -25 degrees...lol..soon when the sun shine again I will resume my project and new ones too... regards faroun

To keep it from bulging use a threaded rod from top shaft to middle to bottom and leave shafts in wheels. Also the PVC or ABS could be cut in quarters and all spokes could be left and a little slit cut made into the blades to fit in between spokes. It wants to be as lightweight and as sturdy as possible.

I see allot of PVC VAWT's with the blades crammed together like on this, I also see 55gal. drum ones that have two blades stacked up with more drums. Is one really better or are they just two different ideas.

@al_taka:Looking at the photos, I'm thinking that you really cant turn the vanes any more towards the *outside* of the rim because you wouldn't have anything to attach to the rim. The way the vanes are constructed requires the orientation shown. If the builder had left a small ring at either end, that ring could be attached to the rim, allowing the vane to be rotated so that the concave face presents more 'windwardly', but this would make constructing the vanes MUCH more difficult, with little realized difference.

@Faroun: Have you considered twisting the vanes along their length? As half a pipe, the vanes should have much greater flexibility around their vertical axis. You could rotate the rims w/respect to each other to twist the entire assembly. Would be interesting to see if it had any effect.I like this design a lot, Nice Job!

THanks Phred, i have modified this project to resemble the v8-4". so i can adjust it back do to many hole in the vanes . in order to try your suggestion i have to start fresh. at this time i am busy with the Column-R project, it is a vawt that uses airfoil to create rotation. check it out

Great design! I was noticing the other day that wind gets greatly accelerated when it goes around the corner of a building, so I thought this would be the ideal place for mounting one of these turbines. How much vibration do they make? Would it cause structural problems for a building it was mounted on?

Not sure if someone has suggested this or not but what if you add a couple more rims to help prevent the bulging at higher RPM? Would you also get a better result using ABS instead of PVC pipe? It's been a while since I have looked but I remember the ABS being thicker and harder/ stiffer. Maybe less flex involved. Great job on the explanation, thanks!

while testing with My V10, I did try more rims, there was less bulge but not totally gone. that is why I developed the cigar shape. Not just eliminated the bulge, it also increased the rpm and blade area all at the same time. my V8-3" and v8-4" are a better design. thanks for you advice and great and helpful comment. best regards

hi faroun and thanks for the details instructables. Just a quicjk question to be clear, your v10 is not a "version 10" being the evolution iof v8.3 and v8.4?? I'm a bit lost between all your models and as it seems you did a lot of testing, which is the more efficient one? According to this last comment v8-4 is the best. Is that right? Thanks a lot

the link and i are the same person. i was only pointing out that one of my turbine was put on display at GSD. greenenrgywindturbine.com ,wrapwind.com, collectwind.com, windhijacker.com, smoothwind.com, fawts.com, fhawt.com, windfriction.com, wintornado.com vawt.tk all my web sites. but instructables.com is one of my favoraite sites for others to see us and our creations. i hope you are learing few things. best regards Sam, Faroun, Emagnets, Vawt ....many names same ideas to share.

The BEST way is to make your own alternator with an increased diameter of the stator/rotor with more number of magnets and use thinner coil (about 24AWG) with more windings so it will produce higher voltage in lower RPM. and connect them in parallel for more amperage.

hey Faroun i understand u have i license, im a 13 year old lving in New Jersey i wanted to know if i could use ur V10 in my science project on energy, ofcourse i will have a link going back to u all i,m asking for is your permission to use ur V10 for my project

I am happy to be part of your science project. you have my blessing and permission. be carefull when handling power tools, i am sure an adult will giude you through your project. Exccellent Choice and good luck.

I was thinking... would it be possible to put it on it's side in a river or something, I just heard that water is denser, and so has more energy than, air do you think it would work? p.s.- my idea - pretend it's copyrighted please thnx

hi there guys, i have made a new wind turbine style and call it The "FAWT Silo" (fixed axis wind turbine Silo) maybe later i can do an instructable on it, but for now you can visit my site at www.wrapwind.com to see how i did it. regards

I'm laying out my vane design right now and I came across this step above. What was the reason that you have the open end of the vanes facing mostly into the turbine instead of having the open end facing the incoming air? Also, I chose an odd number of vanes so birds will see very little light through the spinning turbine.limiting their kamikaze effect. Your advice on wasted air inside turbine made me think to use 4 to 6 inch pvc vanes. Thanks for your advice Al
